Ultima Rear Brake Wheel Cylinder LHS R/L (JB3158) for Toyota Dyna BU6# & BU100 Single Rear Tyre 1985–1999

This Ultima Rear Brake Wheel Cylinder (JB3158) is designed as a high-quality, direct OE replacement for the Rear Left-Hand Side (LHS) of specific Toyota Dyna light truck models equipped with **Single Rear Tyres (SRW)**. This part is the **Rear/Lower (R/L) or Trailing Shoe** cylinder, which works in tandem with the leading shoe cylinder (JB3156) on the same axle. It fits the Dyna BU6# series (January 1985 to December 1988) and the BU100 series (July 1995 to May 1999). It is crucial to confirm your vehicle uses single rear tyres, as dual-tyre models may require a different part. This cylinder is a vital component in the rear drum brake system, converting hydraulic pressure into the necessary stopping force required by the brake shoes to ensure safe and dependable performance under load.

Features & Benefits:

  • Direct Fit OE Replacement: Designed to match the fit, form, and function of the original equipment wheel cylinder on the LHS Trailing Shoe position.
  • Single Rear Tyre Specific: Correct fitment for Dyna models that are not dual-rear-wheel (DRW).
  • Heavy-Duty Construction: Built for durability and dependable braking performance in light commercial use.
  • Reliable Braking: Ensures accurate hydraulic pressure transfer for consistent and responsive drum braking performance.
  • Corrosion Resistance: Manufactured from durable materials for protection against corrosion and wear.
  • Position Specific: Designed exclusively for the Rear Left-Hand Side (LHS), Trailing/Lower Shoe.
  • Complete Unit: Supplied ready to install with pistons, seals, and boots.

solid dress shoes for the price
Size: 12, Color: Black
solid dress shoes, specially when factoring in price. Fit to my size and work well for rare business dress days at my work. They aren't most comfortable dress shoes ever, but as long as not doing long walks in them, should be fine!

Great shoes (I wear them to work and church) and the pictures don’t do them justice. They look really good in person. Very comfortable and hold up nicely

Decent Work Shoe, But Stitching Flaw
Size: 9.5, Color: Black, Size: 9.5, Color: Black
I like these men's derby shoes for my husband, but I'm not too surprised they are flawed considering they are Amazon brand. Not to say anything bad about Amazon Essentials by any means, since they have great, affordable products available. However, they are obviously not the super expensive men's derby shoes that are out there. I'm grateful to have a lower cost option, hence me getting them, but there were some minor issues. The stitching on the ankle rear of the shoe was a bit off. They are also a thinner faux leather, not as sturdy as a more expensive material would be. For the cost, though, they are exactly what I needed. These will not be returned and will be used for a work event. No complaints from the husband about fit or comfort. And the color and style were as expected.
